Its 48C down to -10C here. Some years get down to -18, but not enough to build for it. That extra 8C has a qualitative difference to the steps that need to be taken for people and structures. The problem this year has been high humidity at that high end, much more than normal. When you have over 40% relative humidity and its over 45C it makes air conditioners work extra hard due the specific heat of the water vapor they are cooling. There were some dessication technologies being talked about last year that would really help as they operated prior to cooling the air but I haven't seen them rolled out yet. I've heard anecdotes about EVs refusing to operate due to battery safety, and public transit shutting down due to insufficient cooling capacity.
